THE EXACT SAME THING HAPPEN TO ME.

went around the track, after i hopped off the 2nd time (probably after 6 hard laps in total) i went around, idling was up n down between 500rpm - 2,500rpm and A SH!T load of black smoke puffing away like a chimney. i noticed if you let the car sit for a while it will go away but once you hit the track again it'll start puffing again. Then let it sit and when you go home its back to normal again. I've also noticed that it struggles when it gets really hot (eg 40 deg summer day) but it doesn't spit out as much black smoke as the time at the track.

Bitch of a thing is to get the car moving while its like that you have to ride the clutch a bit just to get it starting and when your trying to move the car to line up it bunny hops like someone's on L plates !

the solution mentioned earlier is to get a flashpro, from research i've conducted running a little rich is fine but i explained what happen to a mechanic friend he advised that should probably take it easy, just incase ahah so i won't be going again until i get flashpro tuned up

1 question though, when ur driving day to day do you have any burpling when you let the throttle go or when ur downshifting ?
